This tool was designed and built as a portable low cost solution for both small and large aerospace applications. It is made of aerospace grade stainless steel and heat treated on all wear and deflecting components to 38/42 on the Rockwell Hardness Scale. A large variety of interchangeable yokes are available with ranges from as small as 1.00" to 6.00" reach. It has proven itself over the years as a portable rugged solution, for light to medium duty, rivet squeezing applications.

WARNING: Cancer and Reproductive Harm -


I got the 3 reach (THS-30) and while it works great, gets everywhere I need it to, sometimes the jaws need a gentle nudge to retract back open. I suspect its just a very low-tolerance tool and will loosen up a little with time, but that was a minor annoyance for me. Also worth mentioning, it does not come with any yokes (hard points for the jaws) so you will need to buy those separately. Not a complaint at all, just something to note.

Q: Is there a users manual included with the Tatco Hand Rivet Squeezer?

No manual, just a yoke replacement procedure. If you butterfly the handles you can adjust rivet set holder up or down. You can also squeeze handles and rotate set holder with 1/8" rod using side hole on set holder.
